Ozzy’s reaction was pretty great, too: “It doesn’t matter what I feel, the baby’s on its way.” But for the record, he thinks it’s “fabulous” to be a grandfather again. (He already has four grandchildren from his older kids Jessica and Louis.) But this will be Sharon’s first grandchild. That’s what most tickled Piers; he told Jack, “You have made my decade.”

Obviously Jack and Lisa knew she was expecting when they got engaged, and were likely waiting for the pregnancy to become safe enough to announce. But we don’t think that’s the reason they got married; the two seem genuinely in love and like they get a kick out of each other. Lisa’s only tweets about the pregnancy have been to thank friends for their congratulations; Jack’s latest tweet was just a smiley face.
